Subject Description: QW-103.2, Records


Record Number: 12-7


Question(s) and Reply(ies): Background: In the 2006 Addenda to Section IX, it became mandatory to

certify qualification records "by signature or other means as described in the

manufacturer's or contractor's Quality Control System."

Question: Prior to the 2006 Addenda, is a typed signature or means otherthan a written signature on a procedure qualification or performance

qualification record considered certified as required in QW/QB-103.2?

Reply: Prior to the 2006 Addenda, the method of certification for procedure

and performance qualification records was not addressed by Section IX.

Question(s) and Reply(ies): Background: QW-200.1(b) says: "The completed WPS shall describe all of

the essential, nonessential, and, when required, supplementary essential

variables for each welding process used in the WPS."

Question (1): If a WPS is written and qualified for welding P-No.1 material

to itself, is it necessary to specifically mention on the WPS or on the PQR

anything regarding QW-410.64, which addresses the use of thermal

processes for cutting or backgouging when welding on P-No.11A and

P-No.11B materials?

页码，36/40



37/40

Reply (1): No. The fact that the WPS and PQR are for welding on P-No.1

materials precludes the need to specifically describe the use of thermal

cutting or backgouging for P-No.11A or P-No. 11B materials on either the

WPS or the PQR.

Question (2): If a WPS specifies the use of ER70S-6 filler metal, is it

necessary to specifically mention in the WPS anything regarding QW-

404.23, which addresses filler metal product form by specifying that thefiller metal has to be solid?

Reply (2): No. The designation ER70S-6 specifies that the filler metal be

solid wire, and that is sufficient for describing the variable QW-404.23.

Question (3): If a WPS is written and qualified for welding P-No. SA

material to itself, is it necessary to specifically mention on a WPS or on the

PQRs for submerged arc welding anything regarding QW-404.34 that

addresses, when welding on P-No.l materials, the use of active or neutral

flux?

Reply (3): No. The use of active or neutral fluxes only needs to be specifiedon the WPS and documented on the PQR when the base metal is P-No.1.

Question(s) and Reply(ies): Background: Impact testing of welding procedure qualifications is required

by the Construction Code and QW-410.9 applies to the welding process

used as a supplementary essential variable. QW-410.9 requires

requalification for a change from multipass per side to single pass per side.

Per QW/QB-492 Definitions, a pass can result in a weld bead or a layer.

Question (1): Does QW-410.9 regard multiple layer welds as multipass

welds, so that a change from multiple layers per side to a single layer per

side requires a requalification?

Reply (1): Yes, when the single layer is made in a single pass.

Question (2): Does QW-410.9 regard multiple beads in a single layer (as

shown in beads 3, 4, 5, and 6 of Figure QW/QB-492.1) as “multipass”?

Reply (2): Yes.

Question (3): A Welding Procedure Specification is qualified with multiple

layers per side. Can this WPS be used to deposit multiple beads in a single
